Katamari Damacy - Playstation 2
This game is one of my FAVORITES! I love it. Its so bizarre and fun! You're a tiny little alien and you have to put the stars and planets back in the sky. How do you do it? By rolling around collecting objects (like a dung beetle). The more stuff you roll over, the larger your mass grows and subsequently, your environment. You start off in a room rolling up push pins and stuff, then move to the outside rolling up bigger and bigger items (flowers to trees to animals to trucks to houses and eventually islands and clouds). This is all done under time constraints of course. Check it out. Its amazing.
